REEL BODY AND PROCESS FOR PRODUCTION OF REEL BODY

摘要

The purpose of the present invention is to prevent the occurrence of blocking in a reel body. A reel body comprises an anisotropic conductive film (3) which comprises a release base (31) and a resin film (32) formed on the release base (31) and a reel (2) which comprises a wind-up section (21) that winds the anisotropic conductive film and flanges (22) that are respectively arranged at both sides of the wind-up section (21), wherein the anisotropic conductive film (3) is wound by the wind-up section (21) and is placed in a region formed by the wind-up section (21) and the flanges (22), one end (31a) of the release base (31) which is taken in the width direction (W) along the length direction (L) has a protruding part (31c) which protrudes from one end (32a) of the resin layer (32) which is taken in the width direction (W) along the length direction (L), and the protruding part (31c) is in contact with the flanges (22).
